AXLE-NUT.

SPECIFICATION forming part of Letters Patent No. 687,8 57, datedDecember 3, 1901.

VApplication filed March 29, 1901. Serial No. 53,455. (No model.)

To @ZZ whom`l t may concern.'

Be it known that I, JOHN SEUFFERT, a citizen of the United States,residing at Ryde,

in the county of Sacramento and State of Gali-V fornia, have invented anew and useful Axle- Nut, of which the following is a specification.

This invention relates to hub-attaching devices, and has for its objectto provide an improved sectional axle-nut which is arranged forconvenient adjustment, so as to take up wear and prevent looseness ofthe wheel. It is furthermore designed to arrange the parts of the deviceso as to be gripped all at the same time by a wrench in applying andremoving the nut, so as to prevent separate turning of any of the parts,and thereby facilitate the application and removal of the nut.

With these and other objects in view the present invention consists inthe combination and arrangement of parts, as will be hereinafter morefully described, shown in the accompanying drawings, and particularlypointed :out in the appended claim., it being understood that changes inthe form, proportion, size, and minor details maybe made within thescope of the claim without departing from the spirit or sacrificing anyof the advantages of the invention.

In the drawings, Figure l is an elevation of the outer end portion of anaxle-spindle, having an axle skein or box in section and also theimproved nut in section. Fig. 2 is a detail perspective view of the nut.Fig. 3 is a longitudinal sectional view of the adjustable sleeve memberof the nut. Fig. 4 is a side elevation of the axle-engaging nut orcapmember. Fig. 5 is a longitudinal sectional view thereof.

To fully illustrate the application and operation of the present device,there has been shown in Fig. l of the drawings an outer end portion ofan axle-spindle 1, having the usual reduced and screw-threadedouter'terminal 2 and an ordinary axle skein or box 3, mounted upon thespindle. These parts are common and well known and form no part of theinvention.

In carrying out the invention there is proyided a cap-shaped nut 4 inthe shape of a being an external outwardly-directed marginal polygonalshoulder 6 formed at the closed end of the cap and designed forengagement by a wrench in applying and removing the nut. i

As clearly shown by reference to Figs. 4 and 5 of thedrawings, it willbe apparent that the cylindrical body of the nut has its interiorscrew-threaded inV one direction and its exterior screw-threaded in theopposite direction. Y

The adjustable sleeve member 7 is open at opposite ends and isinteriorly screw-threaded to fit the external screw-threads of the capmember or nut proper, the inner external end portion being of polygonalshape, as indicated at 8 in Fig. 2 of the drawings, to correspond withthe polygonal wrench-head portion ofthe cap member. At the outer end ofthe sleeve there is provided an outwardlydirected marginal flange 9,which has a circular outer periphery, and from the outer face of thisiiange there projects a cylindrical rim 10, which is both externally andinternally smooth and of greater internal diameter than the internaldiameter of the screwthreaded .portion of the sleeve. When required, awasher ll may be fitted against the inner side of the wrench-head 6 ofthe cap, so as to be gripped between the said head and the inner end ofthe adjustable sleeve, so as to project the latter beyond the open endof the cap.

As shown in the drawings, the internal i screw-threads of the cap arearranged for a spindle having a right-hand screw-thread,

whereby the external screw-threads run to the left. The sleeve is run uptightly against the wrench head or shoulder of the cap, so that thepolygonal portions of both members correspond, as shown in Fig. 2, afterwhich a wrench is appliedA to the polygonal portions of both members andthe cap member screwed upon the screw-threaded portion of the spindle.As both members are gripped by the wrench they turn together, wherebythe sleeve remains in its original position upon the cap. Thecylindrical rim portion l0 of the sleeve takes over the outer end of theaxle skein or box in the usual manner, while the outer end of the sleevebears against the IOO outer marginal edge of the boX, there being theusual washer 12 interposed between these two parts.

Should the sleeve bind upon the wheel-hub and be turned therewith in aforward direction, the sleeve will be backed off from the hub by reasonof the screw-threads leading toward the outer end of the nut or cap,whereby it is impossible for the sleeve to become interlocked with theWheel sufficiently to also turn the nut proper with the wheel, andthereby bind the entire device upon the Wheel and lock the latteragainst turning.

When the axle-box becomes worn at the end, the amount of adjustment maybe determined by setting the sleeve up against the end of the box,whereby a space is formed between the inner end of the sleeve and thewrench-shoulder of the cap. The entire device is then removed from thespindle and one or more washers ll fitted to the nut and against theinner side of the wrench-shoulder 6, after which the sleeve is replacedand the entire device fitted in place, as hereinbefore described.

It will be understood that it is designed to provide the nuts for bothright and left hand spindles, and in any event the inner and outerscrew-threads of the nut or cap are reversed, so that any movement ofthe sleeve, caused by the binding of the latter upon the wheel-hub, willback the sleeve away from the hub and bind the same against thewrench-shoulder of the nut or cap, thereby interlocking the two membersagainst looseness, and thus preventing rattling of the sleeve. By havinga screw-threaded connection between the sleeve and the cap the former isheld against loose sliding upon the cap, which would result in rattlingof the sleeve and a consequent wear thereon.

What is claimed is- A hub-attaching device or axle-nut, consisting of ahollow cap having its interior and exterior screw-threaded in oppositedirecltions, and also provided with an externallyenlarged polygonalwrench-head at the outer end thereof, and an internally-serew-threadedadjustable sleeve fitted to the externallyscrew-threaded portion of thecap, and that end of the sleeve which is adjacent to the wrench-head ofthe cap, being provided with a corresponding wrench-head, thecorresponding outer marginal portions of the wrenchheads being normallyalined to form a single wrenchhead,whereby both membersare interlockedagainstindependent movement when a Wrench is applied thereto, and themutuallyengaged screw-threaded portions of the cap and the sleeve beingconstructed to back the sleeve outwardly toward the head of the cap forfrictionally interlocking therewith When the sleeve is turnedindependently in the direction ot' the tightening movement of the cap.

In testimony that I claim the foregoing as my own I have hereto affixedmy signatu re in the presence of two witnesses.

JOHN SEUFFERT.
